Razer Leviathan Mini - Won't charge/turn on

Hi, I have owed my Razer Leviathan Mini for about two years now and I started to experience an issue with it about a year ago. When I would attempt to charge it, the charging pulsating red light would come on for about 10 times and then it would give up, so I couldn't charge it and then recently I wanted to try to get it working again and I tried a charging block which I use for my phone that has quick charge so it outputs higher if needed and it charged it just fine as it had a green charge light on the speaker. Then I used it till it ran out (Today from Sunday) I had troubles charging it again so I used the same cable and charging block and I left it charging whilst I was out and it seemed to be charging fine. Once I got back home the device had no charging light on it of any kind and would not turn back on at all. I attempted resetting it (reset button) tried many different cables and charging blocks and still nothing. So, I don't really know what to do and I had searched online for other people may be having the same issue and nothing at all really, so I was hoping someone here might be able to help. Thanks, Kieran
